Cities experience dangerous heatwaves due to the urban heat island effect, where human activities and infrastructure trap heat, making temperatures reach 45°C or higher. To prevent heat-related illnesses, avoid outdoor activities between noon and 4 PM when UV rays are strongest, limit intense workouts to prevent cramps and cardiac strain, consume light meals instead of heavy spicy foods to reduce internal body heat, and drink electrolyte-rich fluids rather than plain water to maintain proper hydration and mineral balance. Elderly individuals and diabetics face significantly higher risks of heat stroke, dehydration, and cardiac complications during extreme heat events.
